INDICATOR-BOLT.`

SPECIFICATION forming part of Letters Patent No. 398,722, dated February 26, 1889.

Application ld April 18, 1888. Serial No. 271,053. (No model.)

` word are formed in white, and the plate is in the city, county, and State of New York, have invented certain new and useful Improvements in Door Bolts or Locks, of which the following is a specification.

My improvement relates to an attachment for a door bol t or lock, whereby the locked or unlocked position of the bolt is made to indi cate whether the closet or room to the door of which said bolt is applied is occupied or unoccupied. or provide it with such a projection that when the bolt is moved it will cover or uncover a portion of a word-such as Unoccupied or Disengaged -and so indicate whether the closet or room lis occupied or not.

My invention will first be fully described with reference to the accompanying drawings, and then pointed out in the claim.

In said drawings, Figure l is an elevation of my improved bolt from the rear side of the door. Fig. 2 is a view of the indicator outside of the door. Fig. 3 is a transverse vertical section of the bolt and indicator. Figs. 4 and 5 are face views of the indicator, exhibiting modifications.

In Fig. 4t a modification of the invention is shown, in which the rst syllable of the word V Disengaged is printed or produced on the sliding plate 7, so that it will disappear into the recess or guide made in the door when the bolt shut, and a similar arrangement is shown in Fig. 5, where the whole word is printed on the sliding plate T,- the tirst syllable being hidden by the recess in the door when the door is bolted.

l may represent an ordinary or any preferred form of door-bolt, which in the present instance is shown provided with a fingerpiece, 2, and arranged to slide in housings 3 and to engage in a hasp,4, on thedoor jamb or post.

5 is an indicator-plate on which is printed or produced in an7 manner the word Disengaged or noccupied, or a similar word. Preferably, th is plate is of opaque glass-such as blue glass-on which the letters of the To this end I so arrange the bolt Y to the free movement of the bolt longitudii the light.

vwith an elongated opening or slot equal at mounted on an extension, (i, of the base of the housing 53. Glass is preferably employed, so that when the gas is lighted in the closet or room the sign will be shown up clearly by The door, of course, is provided least in length to the space occupied bv the word employed,in order t0 disclose the whole word or a part thereof.

At one end of the bolt. l is hinged a plate, 7. Part of the arm 8 surrounding the bolt is so seated 'thereon as to present no obstacle nally, and by reason of the hinging of these two parts together the rotary movement of the bolt is also not interfered with. The bolt in its longitudinal movement, however, to close or open the door will slide the plate 7 so as to uncover the whole of the word Disengaged7 or Unoccupieth as the case maiv be, or else to cover the first syllable of such worth-thus chan ging the in dit-ation and showing whether the closet or room locked or unlocked bythe bolt is occupied or unoccupied.

To prevent manipula-tion of the bolt from the outside, a plate, 9, of clear glass may be seated on the door in rear of the base-plate, 6, and across the aperture made in the door.

This bolt is intended for water-closets in hotels, in private houses, at railway-stations, on board vessels, or for private and other oftices. It can be manufactured at very small expense over and above expense of manufacturing an ordinary bolt.

I am aware that it is quite an old idea to combine with a door lock or bolt a mask, adapted when the bolt is shot so as to fasten the door to uncover an iinlicatingovord to show that the room is occupied; and also that a bolt has been devised, the forward movement ot' which would expose thc letters of such an indicating word through a series.

Having thus desei-lbed my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

The eon1bi1mtion,\vith t door-bolt, ol the xed indicator-plate 5, bearing the Word Disengftged or equivalent Word, and a slide, 7, connected to the bolt and operated thereby, so as to @over the rst syllable of the Word when the bolt is advanced and uncover it when the bolt is retracted, thus giving posi- 1o tive and opposite indications with therespeetive positions of the bolt, as explained.
